Wilting flowers

By , published on August 18, 2015, in Video Format

Wilting refers to the loss of rigidity of non-woody parts of plants. This occurs when the turgor pressure in non-lignified plant cells falls towards zero, as a result of diminished water in the cells. The rate of loss of water from the plant is greater than the absorption of water in the plant. The process of wilting modifies the leaf angle distribution of the plant (or canopy) towards more erectophile conditions.

Lower water availability may result from:

  • drought conditions, where the soil moisture drops below conditions most favorable for plant functioning;
  • the temperature falls to the point where the plants vascular system can not function.
  • high salinity, which causes water to diffuse from the plant cells and induce shrinkage;
  • saturated soil conditions, where roots are unable to obtain sufficient oxygen for cellular respiration, and so are unable to transport water into the plant; or
  • bacteria or fungi that clog the plant’s vascular system.
  • water drowns the plant

Wilting diminishes the plant’s ability to transpire and grow. Permanent wilting leads to plant death. Symptoms of wilting and blights resemble one another. In woody plants, reduced water availability leads to cavitation of the xylem. Wilting occurs in plants such as Balsam and tulasi/tulsi. Wilting is an effect of the plant growth inhibiting hormone, abscisic acid. With Cucurbits, wilting can be caused by the Squash vine borer.

    I love timelapse. But in all my years, I’ve never gotten around to shooting flowers. You’ve done a really nice job here.

      I’ve been experimenting with photography on flowers for the past 3 weeks, and here is the best of what I got. Hope you enjoy!

    Very smooth and relaxing and above all, Inspiring. I’ll have to include some sequences like this in one of my TL videos in the future. I really liked what you did here.
